Channelrhodopsins are key tools in optogenetics. The C-terminal end of Channelrhodopsin-2 extends into the intracellular space and can be replaced by fluorescent proteins without affecting channel function. This kind of fusion construct can be useful to visualize the morphology of ChR2 expressing … See more Channelrhodopsins are a subfamily of retinylidene proteins (rhodopsins) that function as light-gated ion channels. They serve as sensory photoreceptors in unicellular green algae, controlling phototaxis: … See more Phototaxis and photoorientation of microalgae have been studied over more than hundred years in many laboratories worldwide. In 1980, Ken Foster developed the first consistent theory about the functionality of algal eyes. He also analyzed published … See more The natural ("wild-type") ChR2 absorbs blue light with an absorption and action spectrum maximum at 480 nm. When the all-trans-retinal … See more Channelrhodopsins can be readily expressed in excitable cells such as neurons using a variety of transfection techniques (viral transfection, electroporation See more In terms of structure, channelrhodopsins are retinylidene proteins. They are seven-transmembrane proteins like rhodopsin, and contain the light-isomerizable chromophore all-trans-retinal (an aldehyde derivative of vitamin A). The retinal chromophore is … See more In 2005, three groups sequentially established ChR2 as a tool for genetically targeted optical remote control (optogenetics See more • Hegemann P (2008).

WebChannelrhodopsin 2 (ChR2) is a cation-permeable channel protein that enables cell depolarisation in response to blue light. The antibody specifically detects the C terminus of ChR2. The epitope is located intracellularly between amino acids 290 and 309 of Chr2. WebNov 25, 2003 · We demonstrate by functional expression, both in oocytes of Xenopus laevis and mammalian cells, that ChR2 is a directly light-switched cation-selective ion channel. … m. d. henry company
